Browser randomly opens to home on its own

Whichever browser I have installed (set as my preferred browser) will open a browser window without user input (and one is not open), will reset to the home page if a browser is open, and open another tab or window at random. There are no pop ups, no specific sites searched for, just going straight to the home page.

This seems to happen randomly; directly after startup, after hours of use, after opening the browser, during program use, when no program is in use. Its maddening.

The results of the hijackthis scan I ran are captured in the two screenshots below, the active processes in the two below that. Before asking for the logfile from Hijackthis, trust me I tried. For some reason the only logfile that got compiled by hijackthis was empty each time (a fix for that would be good, too). However, I will try to give all relevant data and if I leave something out please ask; I will update as needed. Also, I know the quality of these links kinda sucks; I can provide better quality images either through direcy message or if there is a [ img] function on the page.
